Given numbers are 785,278,417,857

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 785,278,417,857 is 561069330.

Find LCM of 785,278,417,857 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

139 x 785 x 2 x 3 x 857 = 561069330

Therefore, the lowest common multiple of 785,278,417,857 is 561069330.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

785 x 278 x 417 x 857 = 77988636870

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

785 : 1, 5, 157, 785

278 : 1, 2, 139, 278

417 : 1, 3, 139, 417

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,278,417,857, is 1.

Now, the common factors can be found like this.

785:5x 157

278:2x 139

417:3x 139

857:857

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

139 = 139

Therefore, the value for common factors is 139.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 77988636870/(1x139)

LCM = 77988636870/139

LCM = 561069330

Thus, we can understand that the LCM of 785,278,417,857 is 561069330.
